Nah its just statistics. Historically Canadas population has been less than 10% of that of the US, we've almost hit a record of 12% now.

I live in Germany but im from BC so i get hit more often with the "it must snow a lot there!" and i have to explain that it only snows a few days a year and that i'm a cold weather bitch.

Funny story though, i was on a pub crawl in 2018 in London (the real one) and i happen to run into a group of ~20 Canadian soldiers who had also joined it. There was 1 American on this pubcrawl and later in the night he comes up to me in a panic and says "NAME! You're american right!?!" Haha. He had never been the minority before.
